It's a great mantra. For me, it helped me realize I'm dreaming in 2 different ways.

1. In a DILD, when I heard a voice saying something similar.
2. In a WILD, when i was already in a dream, didn't realize it, untill I heard myself repeating this mantra.

Mantras can serve as above mentioned reminders.

But to gain awareness in a dream, you need RCs and daytime awareness.

Short but very effective RC, mantra and awareness question combo http://www.dreamviews.com/dild/13212...ods-dilds.html Happy dreams
